Method of separating the oil slurry from the crude oil

ABSTRACT

A method of separating the oil slurry with the crude oil, which is first to put the oil slurry containing the crude oil into the cracking furnace to heat to 400-700 degree wherein there remains the pressure value of 3 kg inside said cracking furnace such that the crude oil contained by said oil slurry is cracked into gas status; next, cool the oil gas in step  1  and cool it such that the oil gas after being cooled forms the gas and the light crude oil; next guide the gas in step  2  into the gas tank and to guide the light crude oil into the crude oil tank for the usage as the chemical intermediate or to be distillated into the gas oil, the diesel oil or the fuel oil. Besides, the plastic junk could be put into the cracking furnace to high-temperature cracking with the oil slurry as the fuel of indirect heating the cracking furnace to increase the yield of the light crude oil.

FIELD OF THE INVENTION

[0001] This invention relates to a method of separating the oil slurrywith the crude oil, especially refers to a method of separating thelight crude oil and the crude oil which to evaporate the crude oilinside the oil slurry first into the oil gas, and to cool such oil gasinto the gas and the light crude oil.

DESCRIPTION OF THE PRIOR ART

[0002] Usually the crude oil is buried in the deep layer of the earth,when people want to mint the oil, they should first mint the correctlocation of the oil land, next to proceed the dipping of the oil well,after the oil well is being minted, the crude oil could then be dippedfrom the deep layer of the earth and the crude oil being extracted couldthen be delivered from everywhere in the world. Next it will be refinedto become the light crude oil for usage by each countries such asleadless oil, diesel oil, high-order gas oil, etc; however, since suchcrude oil is extracted from the deep layer of the earth, there containslarge amounts of slurry in such extracted crude oil such as the dirt,the sand, the heavy metal as well as other impurities, there contains acertain amounts of weight for said slurry such that it will precipitatein the bottom location of the original oil tank such that the quantitiesof crude oil for cracking inside said oil tank is reduced; besides,since the crude oil is attached on the slurry such that the crude oil inthe crude oil tank could not be used by cracking which is not aneconomical situation. So, in order to extract the crude oil from thecrude oil tank, there is a technology for separating the crude oil withthe oil slurry according to the principle of centrifugal force; however,there is only a small fraction of the crude oil that could be extractedby said technology wherein most of the crude oil is attached on thecrude oil which makes the subsequent processing of the crude oildifficult, it will cause a lot of air or environmental pollutionwhatever to burn it or to discard it. Thus, if it could design atechnology of extracting the crude oil on the oil slurry, it is the mostemergency thing nowadays.

[0003] Thus it is clear that the above-mentioned conventional technologyis not a good method which requires to be bettered. The inventor of thisinvention, after several years' hard-studying, finally invented thisinvention.
